Content

In operation, the cutting guide 700 may be used in a manner similar to that of the cutting guide 300.  However, the cutting guide 700 may only be secured to each of the first cuneiform 210 and the first metatarsus 230 with a single pin or K-wire (not shown), as mentioned previously.  Further, the cutting guide 700 is smaller than the cutting guide 300.  Thus, the cutting guide 700 may be placed through a smaller, less invasive incision.  One advantage to patient-specific instrumentation may be that instruments may be made smaller, since they are not limited to certain sizes.  Many known instruments come in discrete sizes, each of which is designed to accommodate a range of patient anatomic dimensions.  Thus, for given patient anatomy, the instrument must be large enough to treat the anatomy at either end of its range.  This typically requires the instrument to be oversized for many anatomic dimensions it is designed to treat.  Notably, the cutting guide 700 is merely one compact example; other cutting guides may be made even smaller; in some embodiments, cutting guides may be made that have a smaller width between holes (e.g., holes 740 on the cutting guide 700).  As long as the holes are sufficiently far apart to avoid interference of the pins 500 with the operation of the cutting blade, the cutting guide may function appropriately.  Thus, Lapidus and other procedures may be accomplished through a very narrow incision through the use of patient-specific instrumentation.
